俱舍論記 30.148

30.148

「說業相續至無間即生」者，論主答。此後果起，從業所熏相續轉變差別種生，如種生果。謂如世間說果從種生，然果不從已壞種起，亦非從種無間即生，要經多時轉生果。

Regarding "It is said that from the continuum of karma … arises immediately": the author of the treatise answers. The arising of this subsequent fruit is produced from the specific seeds of the continuum and transformation perfumed by karma, just as a fruit arises from a seed. That is to say, as it is said conventionally that a fruit arises from a seed, yet the fruit does not arise from an already destroyed seed, nor does it arise from the seed immediately; it must pass through a long time before successively producing the fruit.
